XFX Radeon HD6770 - random freezes / display problems / crashes
Hello,
So recently i bought a new PC and im having problems with video while playing games. Everything happens randomly:
- most often monitor display is turning off with audio still being played properly (got to reboot pc)
- second to that freezes happen (got to reboot pc)
- rarely "Display driver has stopped working" error pops up (no need to reboot pc)
- freezes for few seconds and then everything is back to normal
- few times little window popped up on the screen saying "Signal frequency out of range. Please change signal timing. etc"
I noticed that i have more chances of experiencing 1 of the above just after reboot from previous crash and starting a game.
Okay, now to the part what i have done sofar.
Already tried a dozen of different Catalyst drivers, previously removing old ones with Driver Sweeper. Overdrive is turned off and i didnt touch any clock. Default setup.
I tried PSU and GPU on another PC for 3-4 hours - no problems, but it doesnt say much anyway. I can play single game for few hours on my PC without any problem as well, then few in a row may happen.
Some of the problems directly imply that refreshing rate can be wrong and GPU is overheating. Note that i have CRT screen with DVI-VGA adapter and refreshing rate is set to 85Hz (already tried multiple ones in the range of 50-115) with resolution set to 1024-768 ingame/desktop, nothing helps. About overheating - i ran the Furmark test as suggested in another thread, it was running for roughly 14 min and temp got stable at 86-87 C - no artifacts. Monitor is just fine (worked like a charm on previous PC) and tried 2 different DVI-VGA adapters.
I ran a Memtest from boot level twice for whole night, no errors.
Re-attached the GPU into the slot to be sure its settled properly together with power cable.
Voltages checked in AIDA64:
- while on desktop - https://dl.dropbox.com/u/43525724/czujnik.png (sorry for no-english here)
- while playing - no change at all
(and im aware of software based sensors not being too accurate, its just all i can do for now and im unlikely to get the proper one)
Latest BSOD log (i had just a couple, this one clearly happened ingame):
privatepaste.com :: Paste ID 36316f055a - "Nie można odnaleźć określonego pliku." means "Couldn't locate "this" file"
By the way, there is so many topics like this in the web, especialy for 6770HD. I found 1 topic where someone had exact same problem on some Geforce GPU and fixed it by imroving voltage by just a little. Not that it has to have anything to do with my problem, but worth a mention i guess.
